Permitting 101: A Contractor's Guide
Understanding permit requirements is critical for compliance, avoiding penalties, and protecting your business. Here's what every contractor needs to know.
Residential vs. Commercial Permits
Residential Permits
- Repairs & replacements (water heaters, fixtures, repipes)
- New construction plumbing systems (permits ALWAYS required, even in unincorporated counties)
- Major renovations involving plumbing changes
- Exceptions: Some rural counties (TX/OK) don't require permits for residential repairs/replacements, but new construction always requires permits
Commercial Permits
- Always required regardless of location
- More stringent inspection requirements
- Higher permit fees
- Additional documentation often needed
City vs. County Jurisdictions
Knowing who regulates your job site is the first step to compliance.
Key Insight: Texas & Oklahoma
In Texas and Oklahoma, unincorporated counties typically do not require permits for residential plumbing work. However, cities within those counties DO require permits. This is why knowing the exact jurisdiction is critical.
| Location Type | Permit Authority | Typical Requirement |
|---|---|---|
| Within city limits | City building/plumbing department | ✅ Permit REQUIRED |
| Unincorporated county (TX/OK) | County (if they regulate) | ❌ Often NOT required for repairs/replacements (New construction ALWAYS requires permits) |
| Unincorporated county (Most other states) | County building department | ✅ Permit REQUIRED |
Penalties for Unpermitted Work
Working without proper permits exposes you and your client to significant risks:
Financial Penalties
Fines ranging from $500 to $25,000+ depending on jurisdiction and severity
Stop Work Orders
Projects can be halted immediately, delaying completion and payment

Liability Alert
Unpermitted work may:
